Woocommerce layout in The 7 theme give only lines...



As my old website was with an error, I decided to create the site in a new environment. All went well, except for the shop page. When you look at my page : http://www.bss-events.nl/?post_type=product you see that the categories are not listed as pictures, but in lines. Also in my page I see the category listing twice. In my backend I only have entered the categories once (First thing on the page)

Can someone explain where I can change the design from lines into pictures? And what I can do to see my categories only once?

Thanx in advance.
